RADIATOR.

SPECIFICATION forming part of Letters Patent No. 772,858, dated October 18, 1904.

Application fi led April 1, 1902. Serial No. 100,935. (N0 model.)

To all whom it may concern:

Be it known that I, HENRY K. AUSTIN, of Reading, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators for .heat

ing by the use of a fluid heating medium, such as hot water and steam, and has for its object to providea radiator adapted to present a substantially horizontal top surface to radiate or direct heat upwardly, said surface being when in use substantially parallel with the floor of the room in which the radiator is located and relatively close thereto, so that it may be used conveniently as a foot-warmer or as a heatradiating base for a vertically-elongated radiator of ordinary form. I

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings',,forming a part of this specification. Figure 1 represents an edge view of a radiator embodying my invention, a portion beingshown in section, the

section being on the line 1 1 of Fig. 2. Fig. 2 represents a top plan view, portions being shown in horizontal section on the plane of line 2 2, Fig. 1. Fig. 3 represents an end elevation. Fig. 4 represents a sectionon line 4 4, Fig.2. Fig. 5 represents aview similar to Fig. 2, showing the radiator made triangular in form for use in the corner of a room. Fig. 6 represents a'partial edge View and a partial vertical section of the radiator shown in Fig. 5, the section being on line 6 6 of Fig. 5. Fig. 7 represents anelevation showing my improved horizontal radiator adapted for use as the base of an ordinary radiator. Fig. 8 represents a partial top plan view and partial horizontal section showing my improved radiator made circular in form. Fig. 9 represents a section on line 9 9 of Fig. 8. Fig. 10

represents-a section on line 10 10 of Fig. 8. Fig. 11 represents a vertical section showing a radiator embodying my invention arranged with its top surface flush with the floor of the room in which it is located, means being shown for conducting air through the radiator. Fig. 5 l2 represents a section on line 12 12 of Fig. 11.

The same characters of reference indicate the same parts in all of the figures.

In carrying out my invention I provide a radiator having a substantially horizontal top (4, having a considerable area of heating-surface adapted to radiate or direct heat upwardly into the room in which the radiatoris located. Below said top I provide suitable means for circulating the heating fluid, such as hot water or steam, horizontally-in contact with the top a, so as to provide for the eflicient heating of said top and the radiation of heat upwardly therefrom. The said circulating means are formed to occupy a relatively shallow space under the top a, so that the entire structure is in such form that it can be placed upon parallel with the floor and so close thereto as to permit the top a to be utilized as a footwarming support or as a base or support for a superposed radiator or radiating structured of ordinary construction. In the embodiment of my invention shown in Figs. lto 12, inclusive, the said circulating means comprise a series of horizontal heating-chambers c 0,- located under the top a, each chamber having a substantially flat upper side 2, forminga part of the top a, and vertical or inclined sides 3 3, connected at their lower ends. Between the chambers c are located air-spaces d d, the sides of which are formed by the sides 3 3 of the heating-chambers and the tops by portions of the horizontal top a, said air-chambers being preferably open at their bottom portions. The heating-chambers 0 0 are provided with suitable connections, whereby the heating fluid may be introduced into and re-' moved from the chambers. The heating fluid may be introduced into the chambers by means of a flow-pipe 6, connected with the heater, said pipe passing horizontally through one end of the structure crosswise of the chambers c and having outlets e, which deliver the the floor of a room with the top a substantially shown in Figs. 1, 2, 3, 4:, 7, 11, and 19.. In 5 and 6, which represent the radiator made triangular in form for use in the corner of a room, I show a flow-pipe 0 which supplies water to one end of each of the series of heating-chambers c. lhc opposite ends of said chambers are connected by a passage 1 With a flow pipe f In the construction shown in Figs. 8, 9, and 10, which show a circular radiator, the chambers 0 0 open at their ends into chambers h ]L, which form parts of the fluid-circulating means, one of said chambers being connected with a flow-pipe a and the other with a return-pipe Means are provided for circulating air through the air-chambers (Z (Z, so that the heat radiated from the sides 3 3 of the heatingchambers may be conducted from the radiator and utilized. To this end I have shown air passages 41, formed in the horizontal top a, said passages communicating with the chambers (Z (Z and permitting the upward How of heated air from said chambers through the top a, the air entering the open lower portions of the chambers. The structure is preferably raised from the floor by short legs 7' j suiiieiently to permit the free entrance of air under the radiators and into the air-spaces (Z (Z. If desired, orifices c" may be formed in the vertical walls of the radiator at the ends of the air-passages to permit the air to flow horizontally into the air-passages, and, if desired, the passages may constitute the sole means of admitting air to the air-chambers, the bottom of the radiator resting directly upon the floor instead of being separated therefrom by the legs It will be seen that by the above-described construction I have provided a substantially horizontal radiating-surface a, which is located substantially parallel with the floor and in such close proximity thereto that the said radiating-surface or horizontal top a may be utilized as a foot-warmer or as an auxiliary radiator, located beneath an ordinary radiator I). When the horizontal top (0 forms a part of a radiator-base, as shown in Fig. 7, I prefer to extend said top so that the margin will project outside of the margin of the bases of the radiators a 6, thus forming a convenient rest for foot-warming purposes.

In Figs. 11 and 12 1 show a radiator of the general form above described adapted for use in indirect heating or radiation, the top a being located substantially flush with the floor and the fluid-circulating means located below the floor. As already stated, the fluid-circulating means shown in Figs. 11 and 12 are substantially such as those shown in Figs. 1, 2, 3, and i. In Figs. 11 and 12 I also show the casing i, which incloses the airspace surrounding the main portion of the radiator, said casing having an air-inlet K in its bottom and one or more air-outlets Z7 in its top, the arrangement being such that air from an external source is supplied through the radiator, heated there by, and allowed to escape into the room above the radiator.

The radiator shown in Fig. 7 may be so connected with the top radiator that the heating fluid will pass first through and radiate heat from the horizontal radiator belore entering the top radiator, or the fluid may pass iirst to the top radiator and may return to the heating apparatus through the horizontal radiator.

I elaim 1. A radiator comprising a series oi heating-chambers, horizontally arranged, means for circulating a heating medium horizontally through said chambers, and a series of airspaces alternating with said chambers, the radiator having a substantially horizontal perforated heat-radiating top covering the said chambers, the walls between said chambers and air-spaces being inclined, the air-spaces tapering toward the top and eonnnnnicating with the perforations of the top.

Q. A radiator comprising a series of heating-chambers horizontally arranged, means for circulating a heating medium horizontally through said chambers, and a series oi air spaces alternating with said chambers and separated therefrom by inclined walls, the radiator having a sul'istantially horizontal heatradiating top covering the said chambers, and provided with air-passages communicating with said airspaces, the said air-spaces tapering toward the top.

3. A radiator comprising a plurality of heating-chambers arranged side by side in a horizontal series, fluid-circulating connections between said chambers, air-spaces between the chainbcrs,and separated therefrom by inclined walls,a substantially horizontal heat-rad iati ng top covering the chambers and air-spaces, and having openings to permit the upward passage of air heated in the air-spaces by the sides of the heating-chambers, the said air spaces tapering toward the top.

In testimony whereof I, have aflixed my signature in presence of two witnesses.
